Wide band antenna

A wide band antenna comprising a signal generator coupled to a feed region of at least one antenna element comprising upper and lower loops. Upper loop comprising a first conductive loop element defined by an upper conductor and a first conductive blade tapering outwardly forming a flare portion adjacent a distal end of the upper conductor. Lower loop comprising a second loop defined by a base conductor and a second conductive blade tapering outwardly forming a flare portion adjacent a distal end of the base conductor, first and second conductive blades defining, between their facing edges, a notch opening outwardly from feed region. The method comprising matching an antenna element impedance to the transmission line; selecting an antenna element cut-off frequency; selecting an upper conductor length, and subsequently selecting dimensions of the upper loop such that they are substantially equal to a wavelength corresponding to the selected cut-off frequency.
